When trading on Binance, I get this message “APIError code = -1021, msg = Timestamp for this request is outside of the recvWindow”. What am I doing wrong?
You need to sync the time of your device, preferably with a NTP server. Binance is super sensitive about time.
When entering my Pushover app key and user key, I am told: “pushover: invalid recipient”. Why is that?
You will need to install the Pushover app on at least 1 device (in other words: you will need to register at least 1 device with Pushover).
